Abstract
Abstract A longitudinally and laterally extensible camping trailer formed by a collapsible body supported on a chassis whose rear end is mounted on a set of wheels, the front end thereof being hitchable to a vehicle. The body includes a box-like main housing affixed to the chassis and a similarly shaped sub-housing of slightly smaller volume receivable within the main housing and pivoted thereto, whereby when the sub-housing is rotated 180* about its pivot, the main and sub-housings together form a longitudinally elongated chamber having an open side. Also pivoted to the main housing are a plurality of housing segments which in the collapsed state internest within the main housing, and in the expanded state define a bay section enclosing theopen side of the chamber and laterally expanding the volume thereof.
